COMBINED LATHE AND DRILLING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 251,945, datedJanuary3, 1852.

Application filed March 21, 1881. (Modem To all whom it may concern:

Be it known that 1', JOHN F. RAKEs, of Greenup, in the county of Greenupand State of Kentucky, have invented anew and Improved Combined Latheand Drilling-Machine, of which the following is a full, clear, and exactdescription.

My invention consists in a novel construction, arrangement, andcombination of devices whereby a reciprocating drilling-machine isproduced and provision is made for converting the frame of thedrilling-machine into the frame of a lathe, and for driving the lathe bythewheel used for operating the drill,as hereinafter more particularlydescribed.

In the accompanying drawings, Figure ltis a side view of an apparatusembodying my a socket and serves as a drill-holder.

Fig. 5is ahorizontal section in the line 2 zof Fig. 1. Fig.6 is a detail view.Fig. 7 isa horizontal section taken in the line to w of Fig. 1.

- Arepresents a frame or standard, made preferably of cast-iron, andprovided with three legs, B B B. The leg B is inclined at an angle ofabout forty-five degrees, and is permanently attached to the standard A.The two legs B are connected by a brace, b, so as to resemble the letterA, and are provided with a screw-rod, b and hand-nut b above the braceb, for clamping the upper ends to the frame or standard A.

In the upper portion of the standard A there are two arms, a a, in whichworks a vertical shaft, 0, thelower end of which is provided with The upfrictional retarding'dogs, which engage with said concave part.

To the part D is attached one end of a' spring, E, whichis coiledseveral times around said part D and has its other end attached to thestandard A. Below this spring is attached one end of a rope or cord, Ewhich is wound around the part D in an opposite direction from the cgilof the spring. and then passes over a pulley, e, and down to a treadle,e pivoted to the leg B. When the treadleis pressed down the unwinding ofthe rope or cord turns the shaft (.3 in one direction,so as" to rotatethe bit or drill carried by the lower end of said shaft and winds up thespring E. When the pressure on the treadle is removed the unwinding ofthe spring moves the loose part D of the clutch in the oppositedirection, and the shaft 0 and part D remain stationary, while the pawlsd slip around the inner surface'of the part D untilthe first position isattained, and then they again engage with said surface, and thefirstlmotion is repeated. By this means a reciprocating rotary motion isimparted to the part D? and an intermittent motion in one direction tothe part D and the shaft 0. v

In the lower portion of the frame or stand ard A there are two arms, aa, in which a screw, G, works loosely, and carries at its upper end afeed-table, f. On the screw G, between the arms, is a hand-wheel, g, byturning which the feed-table is raised or lowered, as desired. The tablef is prevented from turning by means of a notch engaging with a rib onthe standard A.

Pivoted tothe standard,nearthelower arm, is a lever, h, which is curveddownward under the hub of the wheel 9, so as to be used as a cam. Whenthe feed-talole is at rest the hub of the wheel grests on the lower arma When the table contains work to be drilled or bored it is fed up tothe drill or hit by raising the lever h, so as to lift the wheel 9, andwith it the screw and table.

The standardA is formed with a web, 0;, extending rearward from end toend. The A- shaped leg-frame TB is attached to the lower end of thestandard by clamping the lower end of said web between the upper ends ofsaid legs too by means of the hand-nut b on the screw-rod W, as beforedescribed. When it is desired to use the standard A as aframe for alathe the legs B are removed from the lower end and placed at theopposite end, which is provided, near the corner thereof, with a notch,a, and a hook or projection, 19. The legs are inclined outward from theframe, which then lies hori zontally, and the notch it rests on the rod11 and the hook or projection 19 lies between the upper ends ofthelegs,which are then clamped, as before described.

The lathe-heads are carried by a bar, J, at the ends of which are arms i'i, provided with notches at their ends, which engage with the web '0,as shown in Fig. 1. Thislathe attachment may be readily placed. inposition and removed, and it may also be used when the standard is in anupright position, in which case the bnrJ is provided with a leg, J Thelathe is driven by a band, I, from the fly-wheel G to a pulley on thefixed head K. When the machine is in an upright position the treadle cis arranged as shown in Figs. 1 and 2. When usedin ahorizontalpositionthe treadle is arranged at about ninety degrees from theposition shown in said figures, so as to bring its free end nearly underthe pulley c.

The movable head K is arranged to slide on the bar J and to beheld inplace by a wedge or key in the usual or any suitable manner. It isprovided with a feeding device consisting of a plate, M, carried bya rodor bar, m, working in lugs or arms on the head, and a curved lever, B,arranged and operating in a similar manner to the feeding device abovedescribed. By this means provision is made for using the latheattachment for drilling and boring purposes.

Having thus desc-ribed my invention, I claim as new and desire to secureby Letters Patent 1. Themetallic frameor standard A, formed with the web12 and the arms a a and a a in one piece with said standard, as shownand described, for the purposes specified.

2. The combination, with the frameorstandard A and arms a a, of thevertical shaft and drill-holder O and the fly-wheel 0 provided withremovable counterbalance-weights c arranged as herein shown anddescribed.

3. The combination, with the frame A and the shaft C, ofthe clutch D D,dogsd d, spring E, and rope or cord E as shown and described, for thepurpose specified.

4. The combination, with the frame A, shaft 0, and clutch D D of therope or cord E pulley e, treadle e ,and diagonally-inclined rear leg, B,when arranged and operating as herein shown and described.

5. The removable and adjustable leg-frame, consisting of the legs B Bbrace b, screw rod or bolt b ,and hand-nut If, in combination with theframe or standard A, provided with the web v, notch 12, and hook orprojection 19, as shown and described, for the purpose specified.

6. The combination, with the frame A and arms a 00 of the feeding deviceconsisting of the table f, screw Gr, hand-wheel g, and curved lever h,arranged and operating as shown and described, for the purposespecified.

7. The combination, with the frame or standard A, of the latheattachment consisting of the bar J, provided with the notched or forkedarms 6 i and carrying the lathe-heads K K as herein shown and described.
